Specification of Letters Patent.

Patented Aii 7', 1906.

Application filed October '7, 1904. Serial No. 227,544.

To all whom it may concern:

Be it known that I, JAMEs G. SMITH, a citizen of the United States, residing at Covington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Lubricating Devices for J ournal-Boxes, of which the following is a specification.

My invention relates to an automatic lubricator for journal-boxes.

This invention particularly relates to an improvement over the device shown in my former patent, No, 634,860, granted October 10, 1899.

The features of my invention are more fully set forth in the description of the accompanying drawings, forming a part of this specification, in which- Figure 1 is a central vertical section. Fig. 2 is a top plan View. Fig. 3 is a perspective View of the tray. Fig. 4 is a central vertical section through the supporting-legs.

1 represents the cellar of a journal-box of a locomotive, for instance. This cellar may be of any shape. I forma waste-bearing tray 2 shaped to fit the cellar, said tray bein provided with semicircular ends 3, whic are lined with the wearing-strips 4. The tray is preferably of brass or sheet metal and the wearing-strips of wood or similar material to prevent the semicircular ends from grooving the axle.

5 represents the car-axle, and 6 the carbrass.

7 represents a section of the support for the journal-box.

In my first-named patent the tray is provided with elliptic springs G, designed to form self-adjusting supports for the tray. I have found that these springs continually break and bend from shape and are unsuitable. Therefore I have sought to provide an oiltray with self-contained spring-legs, as many as desired, and adapted to stand on the floor of the cellar and support the tray and in which the coil-springs are not exposed either in the tray or in the cellar, the spring-legs being projected from the bottom of the tray, so that the tray can be simply placed in the cellar and automatically compressedinto position. The tray of course is filled with packing (not shown) which is saturated with oil and which engages the axle.

bottom of the tray and soldered thereto.

Into the open end of the tube 8 is inserted an upwardly-opening tube 9, and within and between these tubes is placed a coil-spring 10. To prevent the tube 9 from coming out of the tube 8, the tube 9 is provided with a flanged ring 11 at its u per end, and the tube Sis provided with a anged ring 12 at its lower end of less diameter than the ring 11. This form of leg is entirely self-contained and automatic in its spring action. It is obvious that as the outer tube 8 is fixed to the bottom of the oil-tray this tube 8, projecting up into the bottom of the oil-tray, does not move relative to the oil-tray, but that the oil-tray and this tube 8 move upwardly or downwardly as a unit upon the telescoping tube 9, the spring of course giving the proper compression. The telescoping member 9 has a foot 16 adapted to stand on the floor of the cellar and support the tray therein. Although not essential to the practical operation of the device, I prefer to place in the bottom of the tray a spring-platform 13, having four cups 14 in the respective four corners, into which fit the springs 15, seating upon the floor of the tray. The purpose of this is to stir up the packing in t e tray independent of the adjustment of the packing vertically with the tray. This tubular form of leg permits the under telescopic member to be telescoped substantially its entire length within the upper telescopic member, which ermits the floor of the waste-bearing tray to 'e near the fioor of the cellar initially, thus utilizing practically the entire depth of the cellar as a Waste-contained space.

It will be noted that in the preferred form two or more independent spring-controlled telescoping legs are shown. independent yielding action at each of the points of support, the advantage of whichiis obvious.

Having described my invention, I claim- 1 In a lubricating device for journalboXes, an oil-cellar, a waste-bearing tray fitting said cellar, an inverted tube attached to the bottom of said tray, a telescoping member inserted in said inverted tube adapted to stand on the floor of the cellar and support This gives an the tray, a coil-spring between said telescoping members and means for maintaining said telescopic relation whereby the tray is provided with a self contained, s ring-con- 5 trolled telescopic leg, substantia y as described.

2. In a lubricating device for journalboxes, an oil-cellar, a Waste-bearing tray fitting said'cellar, an inverted tube attached to Io the bottom of said tray, a telescopic mantle inserted in said inverted tube adapted to stand on the floor of the cellar and support mounted on springs upon the tray, substantially as described.

In testimony whereof I have hereunto set my hand.

JAMES G. SMITH.
